Study on the Evaluation Model for a Local Residual Risk Level at Each Local Government in the Tokyo Inland Earthquake Area

~Study on Applicability of the Framework of the Enterprise Risk Management (ERM)~

Abstract

Countermeasures for disaster mitigation or disaster risk reduction are in progress after the Great East Japan Earthquake and other disasters and it is assumed that residual risks at local level have been decreased by those efforts. However, there has been few research for evaluating “Local Residual Risks”. The authors have currently been conducting a research to develop a model to evaluate the Local Residual Risk against large-scale disasters such as Tokyo Inland Earthquake and Nankai Trough Earthquakes. In this connection， this paper presents the results of preliminary consideration about the development of simplified and prototype model to analyse “local residual degrees of crisis” for four risk scenarios by an earthquake.
